Features of Rosemount 3051S DP Level Technology

ERS™ System

Electronic Remote Sensor (ERS™) Systems provide DP Level measurements by calculating differential pressure from individual pressure readings. This solution eliminates the need for long capillaries and heat tracing, reducing response time by up to 90%. The sensor system is synchronized for DP calculation, easily connects with cable, and can be independently installed and serviced for simple installation and maintenance.


Thermal Range Expander

Thermal Range Expander enables pressure and level measurements in high temperature processes. This seal system uses two different fill fluids, extending the operating range of the transmitter from temperatures ranging from -75 °C (-103 °F) to 410 °C (770 °F). With an improved response time of up to 46%, thermal range expanders simplify installation and reduce cost by eliminating impulse piping and heat tracing.


Wireless Technology

With Wireless Technology, you can add new measurement points easily and cost-effectively in many areas of the plant including those that were previously inaccessible. This information allows you to better optimize your level measurements and reduce personnel exposure to hazardous environments. Get coverage over larger areas with long-range communication options up to 1 km (2/3 mi) between devices.


Diaphragm Seal System

The Diaphragm Seal System protects transmitters from hot, cold, corrosive, erosive or viscous processes. Seals are available with differential, gage and absolute pressure transmitters. Advanced welding and assembly techniques prevent weld corrosion and improve seal strength to deliver reliability and performance in the toughest applications.
